Codes 1992mazda mx-3 with a v-6 1.8L. reading codes by connecting ten slot with ground slot in the diagnose box under the hood by drivers side shock tower. ihave found out the code 5 is a 05 code nock sensor! but i cant find a pict of where it is located? my car has been idling rough ( to low), but it runs fine! it also has 155,000+ miles on it may it be time for a timing belt? thanks for the help. mx3farley

Actually the knock sensor has nothing to do with the idler
but yes you are right the code # 5 means knock sensor problem
most of times knock sensor is located on either side of engine block but if you don't know how it looks like just buy a new sensor and compair it with the one on your car, if you are planing to instal new sensor is ok but if codes keeps coming on then it migh be the circuit from sensor to computer or the computer it self, but again i don't belive it has nothing to do with idle problem. hope and this help
